Alstroemeria plant named ‘Tesantarc’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Tesantarc’, characterized by its upright, somewhat outwardly spreading and uniformly mounded plant habit; sturdy and strong plant form; moderately vigorous growth habit; freely branching habit and relatively short internodes; dense and bushy appearance; large and numerous white-colored flowers with dark red-colored stripes and held above the foliar plane on relatively short flower pedicels; and good garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘TESANTARC’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, grown typically as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Tesantarc’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to create new freely-flowering potted garden Alstroemeria plants with uniform plant habit and attractive flower coloration.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in Heerhugowaard, The Netherlands in April, 2006 of a proprietary selection of Alstroemeria hybrida identified as code number Pa6028x002, not patented, as the female, or seed, parent with a proprietary selection of Alstroemeria hybrida identified as code number Pb6903x035, not patented, as the male, or pollen, parent. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heerhugowaard, The Netherlands in April, 2007.

Asexual reproduction of the new Alstroemeria plant by rhizome divisions in a controlled greenhouse environment in Heerhugowaard, The Netherlands since September, 2007 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tesantarc’. These characteristics in combination distinguish ‘Tesantarc’ as a new and distinct Alstroemeria plant:

-   -   1. Upright, somewhat outwardly spreading and uniformly mounded         plant habit.     -   2. Sturdy and strong plant form; moderately vigorous growth         habit.     -   3. Freely branching habit and relatively short internodes; dense         and bushy appearance.     -   4. Large and numerous white-colored flowers with dark         red-colored stripes and held above the foliar plane on         relatively short flower pedicels.     -   5. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria have broader leaves than         plants of the female parent selection.     -   2. Plants of the new Alstroemeria and the female parent         selection in flower color as plants of the female parent         selection have pink-colored flowers with light yellow-colored         centers.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria have broader leaves than         plants of the male parent selection.     -   2. Plants of the new Alstroemeria and the male parent selection         in flower color as plants of the male parent selection have         white-colored flowers without stripes.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Tescreda Improved’, disclosed in U.S. Plant Pat. No. 24,127. In side-by-side comparisons, plants of the new Alstroemeria differ primarily from plants of ‘Tescreda Improved’ in the following characteristics:

-   -   1. Plants of the new Alstroemeria have broader leaves than         plants of ‘Tescreda Improved’.     -   2. Plants of the new Alstroemeria and ‘Tescreda Improved’ differ         slightly in flower color.     -   3. Plants of the new Alstroemeria have shorter flower pedicels         than plants of ‘Tescreda Improved’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Tesantarc’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown during the winter and early spring in 4.6-liter containers in a glass-covered greenhouse in De Kwakel, The Netherlands. During the production of the plants, day and night temperatures averaged 12° C. and light levels averaged 7,000 lux. Plants were 22 weeks old when the photograph and description were taken.
